How to relocate the UPS mainframe and battery in the computer room? in view of this problem, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

In order to ensure the continuous, reliable, safe and scientific transition of the network operation system of the computer room, the scientific, reasonable and orderly relocation plan must be strictly implemented in the relocation of UPS batteries, and the related work must be completed in a short time, which is very challenging. The following share the steps and measures of the relocation of UPS hosts and batteries in the computer room.

Learn about UPS mainframe and battery equipment first.

The UPS mainframe and the battery are running normally, but the service life of the battery pack has exceeded its service life. In order to avoid battery aging, the impact of relocation on the operation of UPS mainframe power supply system and the guarantee of UPS backup time.

Make a relocation plan

Implementation process

On-site investigation → communicates with Party A's technical personnel on the spot → determines the implementation plan → analyzes the equipment and → formulates the emergency plan.

The process is mainly based on the needs before relocation, mainly a detailed understanding of the current system equipment, the operation of the system. Make detailed relocation plan and emergency plan according to what you know.

The engineer understands the current situation of the user's computer room and the specific requirements after relocation. Fully consider the various situations that may occur in the implementation process, and customize a detailed and feasible migration implementation plan to minimize the impact of computer room migration on users.

The technical staff of UPS manufacturers are required to cooperate closely in the process of relocation.

In order to ensure that the relocation work will be carried out smoothly, orderly and safely, we will formulate a detailed relocation process, carry out a meticulous division of labor, and arrange the specific work to the people and the responsibility to the people.

Personnel organization and arrangement

UPS battery relocation work by the computer room information center is responsible for the overall coordination, set up a general director of the relocation work.

There are four groups:

Working Group of computer Room Construction Units

Working Group on equipment relocation

Equipment debugging working group

Expert group

The specific division of labour is as follows:

1. Commander in Chief

Responsible for implementing the work schedule of each unit according to the relocation plan schedule, coordinating the interconnection of the work of each unit, timely adjusting the situation, and coordinating the overall relocation work.

2. Computer room construction working group

According to the requirements of the battery (12 groups, a total of 256) one by one in place.

3. Working Group on equipment relocation

Responsible for the relocation of safe, intact and complete equipment (batteries), disassemble from the original computer room, gently transport it into the new computer room, place the equipment (batteries) and connect them in place.

4. Equipment debugging working group

It is composed of engineers of the original equipment maintenance unit, who is responsible for the shutdown of the original UPS, testing and debugging of the UPS circuit and performance.

5. Expert group

Observe the whole relocation process, timely find and correct some non-standard and unscientific behavior in the relocation work, and be responsible for dealing with the occurrence of emergency situations.

Dismantle the handling tools

Detailed implementation plan

1. Implementation process

2. Set the implementation time

As the number of batteries replaced is relatively large, the weight of the battery is also relatively heavy; and considering the construction conditions of the site, the installation work is difficult, plus the preparation work before installation and the debugging work after installation, so it is necessary to give a certain construction time.

UPS removal steps

1. Self-check the relocated UPS and battery, and lay the battery connection line from the primary battery to the new battery.

2. UPS is turned off, and the voltage is measured with a multimeter to confirm that the input and output are open and off.

3. The battery switch is closed.

4. Begin to remove the input and output cable and connect the battery.

Carry and transport

1. The dismantled equipment is packed in a paper shell. Put the spare parts in a sealed bag and label them.

2. The removed UPS mainframe and battery are transported separately.

3, shock absorption treatment, put the damping pad on the hydraulic vehicle to ensure that the vibration to the equipment is reduced in the process of transportation.

UPS host installation

1. Connect the input A, B, C phase fire line, N line and PE line to the user terminal strips mA, mB, mC, mN and PE of the stand-alone POD, respectively.

2. Connect the output A, B, C phase fire line, N line and PE line to the user terminal strips oA, oB, oC, oN and PE of the stand-alone POD, respectively.

3. Remove all the short copper bars on the UPS input and output terminal strip, connect the UPS terminal strip of the stand-alone POD and the same screen print terminal on the UPS input and output terminal strip one by one, and connect two PE terminals on the UPS input and output terminal strip with the PE terminal of the stand-alone POD.

UPS host installation

1. Make sure that all input and output switches outside the UPS are in the off position.

2. Connect battery cable.

Optional battery module (2)

1. Take out the one-minute multi-battery cable assembly of the UPS, and plug the plug marked "Battery Module 1" and "Battery Module 2" on the cable into any battery interface on the rear panel of the two battery modules respectively.

2. Ground the end of the battery cable marked as "UPSPE" nearby.

3. One end of the battery cable marked "BAT+", "BATN" and "BAT-" is connected to the "Bat+", "BatN" and "Bat-" terminals of the UPS input and output terminal strip respectively.

4. Tighten the fixing screws on both sides of the battery interface of the battery module with a screwdriver to prevent the battery cable from loosening or falling off.

No battery module selected:

Connect the "+", "N" and "-" terminals of the external battery with the "Bat+", "BatN" and "Bat-" terminals of the UPS input and output terminals respectively.

Several problems should be paid attention to in battery removal, installation and handling:

1. Pay attention to personal safety and equipment safety. We must understand the site situation before construction and avoid affecting the normal operation of other equipment during construction.

2. in the process of carrying the battery, we should pay attention to avoid the collision and breakage of the battery, handle it gently, and be operated by two people.

3. As the site space is relatively narrow, pay attention to keep the passage unblocked and pay attention to the environment around Party A to avoid affecting the normal work of Party A.

4. pay attention to the reverse connection of the positive and negative poles of the battery during operation, and the installers should not bring metal objects such as watches during construction to avoid short-circuit fire.

5. Attention should be paid to the installation space and installation light during the construction of the lower layer of the battery rack, and every step should be careful, careful, correct and standardized.

6. the battery voltage should be measured after each set of batteries is installed, and then connected in parallel after each group of batteries have the same voltage. parallel connection of batteries with different voltages is prohibited, and the replaced old batteries should be placed in the position specified by the user. it is forbidden to misplace.

7. the battery terminal should not be too tight or too loose when it is connected. after installing a group, the battery terminal should be pulled by hand to check whether the connection is firm.

8. Keep in touch with the relevant responsible person of the user, and communicate and report to the relevant responsible person in time if you have any questions.

Inspection after battery installation is completed

Mainly check the following aspects:

1. The on-site environment of UPS power room, the placement and connection of batteries.

2. Detect the input and output voltage, current, charging voltage and working status of the UPS host to ensure that all the test data are within the required range of parameters and record them.

3. Confirm that the UPS host and battery are in normal operation, and then carry out the power outage test to detect the automatic switching of the battery and the time of battery power supply.

During the removal, installation and relocation of the battery, the following may occur in the UPS battery:

1. The battery will heat up after running for a period of time.

2. The phenomenon of blistering and leakage may occur after the battery is heated.

Power-on debugging

This boot step is suitable for booting the UPS when the UPS is completely powered off. The steps are as follows:

1. Close the output switch and input switch outside the UPS in turn. At this point, the LCD displays the startup screen and the rectifier starts. About 30 seconds after the rectifier enters the normal operation state, the rectifier starts up.

2. Press the ON key for 2 seconds

At this time, the inverter starts and the inverter indicator light flashes green. After the inverter runs normally, the UPS switches from the bypass power supply state to the inverter power supply state, the inverter indicator light is always green, and the UPS enters the normal mode.
